[RFC PATCH v2 1/4] kvm: uapi: reserve VM-plane and VBS hypercall numbers

Reserve the paravirt hypercall numbers used by the KVM VM-planes and VBS
(Virtualization-Based Security) host support:

  13  KVM_HC_VM_PLANES_CONFIG    configure plane memory (serviced by the VMM)
  14  KVM_HC_VM_PLANES_ACTIVATE  create+activate a plane vCPU (serviced by VMM)
  15  KVM_HC_VBS_VTL_CALL        normal plane -> secure plane
  16  KVM_HC_VBS_VTL_RETURN      secure plane -> normal plane

This patch only reserves the numbers; the handlers are added separately.
